Description

Technical Field

[0001] This utility model relates to the field of building hoisting equipment technology, specifically a building construction hoisting device. Background Technology

[0002] Construction hoisting equipment is essential for high-altitude operations, typically consisting of a base frame, suspended platform, drive structure, and hoisting structure. These devices are widely used in building exterior wall construction, maintenance, and cleaning, effectively improving construction efficiency and safety.

[0003] Existing hoisting equipment still has some shortcomings in actual use. During the lifting process, the suspended platform is prone to swaying due to wind or improper operation, which may cause it to collide with the wall. This may not only damage the wall but also threaten the safety of the workers. In addition, traditional anti-collision structures are simple in design, have limited buffering effect, cannot effectively absorb impact force, and lack a stability adjustment mechanism, which further increases safety hazards. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a construction hoisting device with advantages such as excellent anti-collision performance and high stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a building construction hoisting device, including a base frame and a suspended basket, wherein a gravity block is provided on the top of the base frame, and a triangular hanger is provided on the top of the base frame near the suspended basket, and a hoisting structure for connecting the suspended basket and the base frame is also provided on the top of the triangular hanger.

[0006] The top of the base frame is provided with a drive structure for providing power to raise and lower the hoisting structure basket. Both sides of the basket are provided with basket triangular brackets. The basket door panel is provided on the side of the basket near the base frame. Two fixing plates are provided on the side of the basket near the base frame. Both fixing plates are provided with anti-collision structures on their front sides to support the wall and prevent collisions.

[0007] Furthermore, the base frame is divided into upper and lower layers, and the bottom of the gravity block is embedded in the bottom layer of the base frame. The two anti-collision structures are symmetrically arranged with the hanging basket door panel as the center.

[0008] Furthermore, the hoisting structure includes multiple rope limiting clamps, two guide wheels, and two metal hoisting ropes. The multiple rope limiting clamps are arranged in two rows at equal intervals on the top of the triangular frame. The two guide wheels are arranged at an inclined angle at the top two corners of the triangular frame. The two metal hoisting ropes pass through the two guide wheels and the two rows of rope limiting clamps respectively as traction ropes to pull the basket.

[0009] Furthermore, the two guide wheels are tilted at opposite angles, which facilitates the extension of the ends of the two metal suspension ropes to the top of the two basket triangular brackets at the top of the basket at their respective tilt angles.

[0010] Furthermore, the drive structure includes a servo motor, two triangular supports, a drive shaft, two rope reels, a driven gear, an output shaft, and a drive gear. The servo motor is fixedly mounted on the top of the base frame, the two triangular supports are fixedly mounted on the top of the base frame, the drive shaft is movably mounted between the two triangular supports via bearings, the two rope reels are both mounted on the shaft of the drive shaft, the driven gear is fixedly mounted in the middle of the drive shaft, one end of the output shaft is connected to the output end of the servo motor, and the drive gear is fixedly mounted in the middle of the output shaft, and the drive gear meshes with the driven gear.

[0011] Furthermore, the other end of the output shaft is connected to a fixed post, and the output shaft and the fixed post are rotatably connected by bearings.

[0012] Furthermore, the anti-collision structure includes a sleeve and two rubber support plates. Each of the two rubber support plates has two sets of connecting rods that are movably installed via a hinge frame on the side near the fixed plate. The four connecting rods are divided into two groups. Each group of connecting rods has a spring retraction rod in the middle, and the two ends of the two spring retraction rods are respectively connected to the two groups of connecting rods through the sleeve.

[0013] Furthermore, the sleeve is equipped with a spring that is connected to both ends of the spring retraction rod. When the two rubber support plates are compressed, the connecting rod is deformed by the action of the hinge frame. At the same time, the spring retraction rod on the connecting rod compresses the spring inside the sleeve to relieve the impact force of the rubber support plates being compressed.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This construction hoisting device, through the installation of anti-collision structures and the synergistic effect of rubber support plates and spring retraction rods, effectively absorbs the impact force when the suspended platform sways, preventing direct collision between the suspended platform and the wall, thus protecting the safety of the wall and the workers. The symmetrically arranged anti-collision structures and gravity blocks enhance the stability of the device, further reducing the swaying amplitude of the suspended platform and improving construction safety.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 The construction hoisting device in this embodiment includes a base frame 1 and a suspended basket 2. A gravity block 3 is provided on the top of the base frame 1, and a triangular hanger 4 is provided on the top of the base frame 1 near the suspended basket 2. The base frame 1 is divided into upper and lower layers. The upper layer is equipped with a drive structure 6 and a triangular hanger 4, and the lower layer is embedded with a gravity block 3 to enhance stability. The top of the triangular hanger 4 is also provided with a hoisting structure 5 for connecting the suspended basket 2 and the base frame 1.

[0022] The top of the base frame 1 is equipped with a drive structure 6 for providing power to raise and lower the basket 2 of the hoisting structure 5. The drive structure 6 is used to provide output pulling force to the hoisting structure 5. The top of both sides of the basket 2 is equipped with a basket triangular bracket 8 and a metal frame for traction connection between the basket 2 and the hoisting structure 5. The side of the basket 2 near the base frame 1 is equipped with a basket door panel 9 for opening the basket 2 to facilitate workers to enter the basket 2. The side of the basket 2 near the base frame 1 is equipped with two fixing plates 10 to support the side plates of the anti-collision structure 7. The front of the two fixing plates 10 is equipped with an anti-collision structure 7 for supporting the wall and preventing collisions.

[0023] It should be noted that the base frame 1 is divided into upper and lower layers, and the bottom of the gravity block 3 is embedded in the bottom layer of the base frame 1. The two anti-collision structures 7 are symmetrically arranged with the basket door panel 9 as the center.

[0024] The hoisting structure 5 includes multiple rope limiting clamps 501, two guide wheels 502, and two metal hoisting ropes 503. The multiple rope limiting clamps 501 are arranged in two rows at equal intervals on the top of the triangular hanger 4 to limit the position of the two metal hoisting ropes 503. The two guide wheels 502 are set at an inclined angle at the top two corners of the triangular hanger 4 to guide the two metal hoisting ropes 503 at an inclined angle to the pulleys at the connecting end of the top basket triangular hanger 8 of the basket 2. The two metal hoisting ropes 503 pass through the two guide wheels 502 and the two rows of rope limiting clamps 501 respectively as traction ropes to pull the basket 2. The metal hoisting ropes 503 mainly function as traction ropes connecting the basket 2 and the drive structure 6.

[0025] It should be noted that the two guide wheels 502 have opposite tilt angles, which makes it convenient for the ends of the two metal suspension ropes 503 to extend at an angle to the top of the two basket triangular brackets 8 at the top of the basket 2.

[0026] Specifically, the drive structure 6 will retract one end of the metal suspension rope 503, thereby enabling the metal suspension rope 503 to achieve the lifting and lowering effect of the basket 2 under the action of multiple suspension rope limiting clamps 501 and two guide wheels 502.

[0027] The drive structure 6 includes a servo motor 601, two triangular supports 602, a drive shaft 603, two rope reels 604, a driven gear 605, an output shaft 606, and a drive gear 607. The servo motor 601 is fixedly mounted on the top of the base frame 1 and serves as the main output power of the hoisting equipment. The two triangular supports 602 are fixedly mounted on the top of the base frame 1 and support the rope reels 604. The drive shaft 603 is movably mounted between the two triangular supports 602 via bearings and serves as the main drive shaft between the servo motor 601 and the triangular supports 602. The two rope reels 604 are both mounted on the shaft of the drive shaft 603 and are used to connect the rope frame for retracting the metal hoisting rope 503. The driven gear 605 is fixedly mounted in the middle of the drive shaft 603. One end of the output shaft 606 is connected to the output end of the servo motor 601. The drive gear 607 is fixedly mounted in the middle of the output shaft 606 and meshes with the driven gear 605.

[0028] It should be noted that the other end of the output shaft 606 is connected to a fixed post, and the output shaft 606 and the fixed post are rotatably connected by bearings.

[0029] Specifically, when it is necessary to lift the suspended platform 2, the servo motor 601 drives the output shaft 606 to rotate, which in turn drives the drive gear 607 to transmit power to the driven gear 605. The driven gear 605 is fixed to the transmission shaft 603, which in turn drives the transmission shaft 603 to drive the two rope reels 604 between the two triangular supports 602 to rotate. This causes the two metal ropes 503 of the two rope reels 604 to retract, thereby lifting the suspended platform 2 through the ends of the metal ropes 503.

[0030] The anti-collision structure 7 includes a sleeve 702 and two rubber support plates 703. Each of the two rubber support plates 703 has two sets of connecting rods 701 that are movably installed via a hinge frame on the side near the fixed plate 10. The rubber support plates 703 are used to form a friction surface with the wall to prevent the suspended basket 2 from directly colliding with the wall. The connecting rods 701 are used to connect the intermediate support rods of the fixed plate 10 and the rubber support plates 703. The four connecting rods 701 are divided into two groups. Each group of connecting rods 701 has a spring retraction rod 704 in the middle, and the two ends of the two spring retraction rods 704 are respectively connected to the two groups of connecting rods 701 through the sleeve 702.

[0031] It should be noted that the sleeve 702 is equipped with a spring that is connected to both ends of the spring retraction rod 704. When the two rubber support plates 703 are compressed, the connecting rod 701 is deformed by the action of the hinge frame. At the same time, the spring retraction rod 704 on the connecting rod 701 compresses the spring inside the sleeve 702 to relieve the impact force of the rubber support plates 703 when they are compressed.

[0032] Specifically, when the suspended platform 2 shakes and hits the wall, the rubber support plate 703 will first come into contact with the wall. The rubber support plate 703 in contact with the wall will transmit the pressure to the fixed plate 10 through the connecting rod 701 due to the squeezing force. While the connecting rod 701 is being squeezed, the spring contraction rod 704 between the two sets of connecting rods 701 and the spring in the sleeve 702 will dissipate the impact force through the reaction force of the spring, so as to achieve the anti-collision effect of the suspended platform 2.

[0033] Working principle: By starting the servo motor 601, the gear transmission drives the transmission shaft 603 to rotate, causing the rope reel 604 to wind up and unwind the metal rope 503, thus controlling the lifting and lowering of the suspended basket 2. During the lifting and lowering process of the suspended basket 2, if there is swaying due to wind or operation, the rubber support plate 703 of the anti-collision structure 7 contacts the wall. Through the buffering effect of the spring and the connecting rod 701, the impact force is offset, keeping the suspended basket 2 stable. The gravity block 3 and the symmetrically arranged anti-collision structure 7 further reduce the sway amplitude, ensuring operational safety.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
